HATCH :non SHIPS AND" Boers l Application-filed september 3,'1930,'ssria1 No. 479,499,5116. in forest Britain December 11,1929:

This invention relatesto `hatches vfor ships and boats of the kind whichhatch bridlesy or webs extend atintervals across `the Vhatch between thec oamings, and are easily removable from-thehatch b y lifting 'themvertically out of housings .forthe ends of the hatch webs. l l' In theusualY existing arrangements, the ends of the-bridles .orfwebs arereceived between lugs or shoes which are secured to the inside oftherhatch coamingsfand which thus form projections extending into lthehatchway. Any such projections reduce the available shipping spacefthro'u'gh the hatchway and shouldbeavoded by reason of the liabil-l ityof such projections damaging cargo or" beingdamaged themselvesbyicargowhich is being loaded or unloadedfthrough thehatchway p Y.

The present invention-has `for its 'object .to

' provide an improved construction ofhatch in which the hatch webs areA,-vconipletely4 housed at .their ends over t'heiru-ll depth,

and are easily removablevfrom the jhatc'h,v while at the Sametimeeliminating the use of any projections lon, the inside 'of the hatchway.For this purpose the hatch webs are made ofextendedV length.V so thatthey are longer than the width :of the `F`hatchway over the full .depthof lthe endsof the hatch web, and each endis completely housed-over itsfull depth in fa housing,` recess or channel which is outside or extendslaterally `-rfxutwards from the hatchway.

In orderthat `the 'invention may lbe more clearly understood, reference`is hereinafter made Vto the accompanying drawings illustrating variousexamples ofthe manner in which my "invention maybe carried vinto effeet.
